Limestone Mill Machine workflow and troubleshooting

Limestone Mill Machine is a new type of high-efficiency, high-precision milling equipment for small and medium-sized mining, chemical, building materials, metallurgy, refractory materials, pharmaceutical, cement and other industries. The machine has strong complete set, high automation level, small environmental pollution, space saving and high screening rate.

Limestone Mill Machine workflow

The Limestone Mill Machine is mainly based on the grinding system of two systems. The two systems are the physical grinding system and the wind sorting system. The close cooperation between the two systems is that the Limestone Mill Machine completes the material grinding and selection. fundamental.

When working, the wool material first enters the small crumb and breaks, and after reaching the particle size of the Limestone Mill Machine (generally below 30mm), the hoist is lifted into the silo, and then the electromagnetic feeder enters the grinder of the Limestone Mill Machine. The chamber is shoveled down and shoveled into the grinding area consisting of the grinding roller and the grinding ring. At this time, the grinding roller is moving with the main shaft, and it is also spinning. Under the action of centrifugal force, the grinding roller will be pressed tightly on the grinding ring of the casing, and the material will be ground under the action of pressure and friction. After that, as the airflow rises, it enters the analysis system, and the qualified material can pass through the analysis machine and enter the pipeline in the upper part of the Limestone Mill Machine, and then the powder separator is selected. Unqualified nature will fall back to the grinding chamber to re-grind, and the remaining gas after the separation will be discharged into the atmosphere after being removed by the bag filter.

Limestone Mill Machine failure treatment

The Limestone Mill Machine encounters problems such as reduced powder output during use, and can be handled as follows:

1, no powder or no powder, low yield

The cause of the malfunction: (1) The locker is not adjusted well, and the seal is not strict, causing the powder to suck up. (2) The blade is worn out and the material cannot be shovel.

Remedy: (1) Check and adjust the lock of the locker and find that the air leak should be scraped. (2) Replace the new blade.

2, the finished powder is too thick, or too fine

The cause of the failure: (1) The blade of the analyzer is seriously worn and cannot be graded. (2) The air volume of the fan is not appropriate.

Remedy: (1) Replace the length of the blade and turn off the air volume of the small fan to solve the rough. (2) If it is too fine, the inlet air volume should be increased.

3. The current of the Limestone Mill Machine rises and the fan current drops.

The cause of the failure: excessive feed, the air duct is blocked by the powder, the exhaust of the pipeline is not smooth, the circulating airflow generates heat, the main current increases, the machine temperature rises, and the fan current decreases.

Remedy: (1) Reduce the amount of feed and remove the wind tunnel powder. (2) Open the large air duct valve, and the temperature of the incoming material is controlled below 6 °C.

4. Limestone Mill Machine main engine is noisy and has large vibration

The cause of the failure: (1) The amount of feed is small. The blade is severely worn, the material cannot be shoveled, and the anchor bolts are loose. (2) The material has a hard impact or no material layer. (3) The grinding roller of the Limestone Mill Machine has serious rounding deformation.

Remedy: (1) Adjust the feed amount and replace the new blade. (2) Replace the feed particle size. (3) Replace the grinding roller and grinding ring.

5, Limestone Mill Machine fan vibration

Causes of failure: (1) Powder or wear imbalance on the blades. (2) The anchor bolts are loose.

Remedy: (1) Remove the leaf powder or replace the blade. (2) tighten the anchor bolt

6. Limestone Mill Machine transmission device and analysis engine oil tank heating

The cause of the malfunction: the viscosity of the oil is large and the oil is thick, and the thread pump oil cannot be used to make the upper bearing lack of oil.

Remedy: (1) Check if the grade and viscosity of the oil match the requirements. (2) Check the running direction of the analyzer.
